Abstract

Seat devices, apparatus, systems and methods for converting vertical single jump seats into bench seats and vice versa, without removing and replacing the seats inside of vehicles, such as in trucks, vans, station wagons, sport utility vans (SUVs), and automobiles. The mechanisms allow for converting the vehicle seats from vertical to bench seats and vice versa without having to physically remove and install different seat arrangements within the vehicles. The conversion between the jump seats with vertical backs and bench seats uses the same seat components and parts. The conversion can take place in seconds and at most a few minutes without using tools.

Description

FIELD OF INVENTION

This invention relates to vehicle seats, and in particular to devices, apparatus, seat systems and methods for converting vertical single jump seats into bench seats and vice versa, without removing and replacing the seats inside of vehicles, such as in trucks, vans, station wagons, sport utility vans (SUVs), and automobiles.

BACKGROUND AND PRIOR ART

Seating arrangements in the backs of vehicles such as trucks or vans is often limited to either or both fixed single seats or fixed bench seats. In order to change a vertical seat to a bench seat would require taking apart the seat to remove it from the vehicle followed by installing a different seat inside such as a bench seat. This amount of work and labor and time would not be desirable for changing out one type of seat arrangement for another. In addition a good amount of tools, such as but not limited to wrenches, pliers, screw drivers, and loose fasteners would have be to used which would also not be desirable.

Some vehicles allow for a bench seat or single seat to fold down to increase floor space. However, the back of the bench seat is being folded down, so that no back remains. As such the folding down bench or single seat also does not turn the bench into a single seat or turn a single seat into a bench seat. The user would still need to dismantle and remove the existing vertical seat to put in a bench seat with a back, and vice versa. As such, the work, labor, time tools and parts would not be desirable.

Thus, the need exists for solutions to the above problems with the prior art.

SUMMARY OF THE INVENTION

The first seat conversion system 1 can be installed by an installer into a vehicle, selected from trucks, vans, station wagons, sport utility vans (SUVs), and automobiles.

Referring to FIG. 1A, the seat conversion system 1 can include a seat foldable seat portion 20 (first platform) and removable vertical backrest 30 (second platform) that are attached to a vertical frame 10. The vertical frame 10 can include left vertical leg 12 and right vertical leg 14 that are mounted to a floor surface 96 inside of a vehicle, with a top portion mounted to an interior ceiling portion (not shown) inside of the vehicle. The vertical frame 10 can include an upper horizontal beam 16 above a lower horizontal beam 18 which extend between the

vertical legs

12, 14.

Once installed, the seat conversion system can initially have a jump seat configuration with a seat portion 20 and backrest 30, as shown in FIGS. 1A, 5A and 9A. The method and process steps of converting the system 1 from a jump seat configuration to a bench seat configuration will now be described.

Referring to FIGS. 4A-6B, the installer can start converting the jumper seat configuration into a bench seat configuration, by unlocking fastener 45. Fastener 45 can be a spring loaded knob fastener, which can be spring biased in an extended position, with a plunger extended outward, and retracts against a spring by rotating the knob and/or pulling the knob outward, which would retract the plunger. Such as rotatable spring loaded knob fastener can be such as but not limited to a Plate-Mount Retractable Spring Plunger, Part#8478A6, by McMaster-Carr Supply Company, Atlanta, Ga.

Such types of spring loaded knob fasteners are shown and described, in various patents, such as but not limited to U.S. Pat. No. 1,154,074 to Strong; U.S. Pat. No. 4,138,150 to Bills and U.S. Pat. No. 6,655,720 to Rampen, which are each incorporated by reference in their entirety. Other types of locking fasteners can be used, such as insertable and retractable L shaped latches, large bolts, screws, and the like, with or without turn knob ends as the bolt heads.

Once fastener 45 is moved to an unlock position, upper telescopic member 42 can slide into lower hollow telescopic member 44, as shown in FIGS. 5A-5C while the upper telescopic member 42 rotates against the bottom 28 of seat portion 20 by mounted upper pivot bracket 26, and the bottom of lower telescopic member 44 rotates against the floor 96 inside of a vehicle by lower floor mounted pivot bracket 48. The seat portion 20 folds downward from a horizontal orientation to be eventually generally against a lower portion of vertical frame 10 by hinges 40 that are mounted to both the seat bottom 28 and lower horizontal beam 18 on the vertical frame 10. The installer can push down on the top 26 of front end 22 which rotates relative to rear end 28 in order to fold the front seat portion 20 relative to the vertical frame 10.

After seat portion 20 is folded downward, the backrest 30 (second platform) is intended to be removed. Referring to FIGS. 1A, 3A, 4A, 4B. 7, 8A, 8B, a pair of L shaped

brackets

70, 74 with rearwardly extending perpendicular flanges can be initially mounted to a rear side 38 of the backrest (second platform) 30 between the top end 34 and the bottom end 36. Additionally, a U-bracket 62 can be mounted to the vertical frame by having a horizontal member 64 mounted on top of the upper horizontal beam 16 of the vertical frame 10. Extending upward from the horizontal member 64 can be bent ends 66 each having through-holes therethrough. The backrest rear side 38 mounted

L brackets

70, 74, with the vertical frame horizontal beam 16 mounted U bracket 62 together is a mounting bracket assembly 60.

Fasteners

80, can be similar to fastener 45 previously described. Fasteners 80 can each be a spring loaded knob fastener, which can be spring biased in an extended position, with a plunger extended outward, and retracts against a spring by rotating the knob and/or pulling the knob outward, which would retract the plunger. Such as rotatable spring loaded knob fastener can be such as but not limited to a Plate-Mount Retractable Spring Plunger, Part#8478A6, by McMaster-Carr Supply Company, Atlanta, Ga.

Such types of spring loaded knob fasteners 80 are shown and described, in various patents, such as but not limited to U.S. Pat. No. 1,154,074 to Strong; U.S. Pat. No. 4,138,150 to Bills and U.S. Pat. No. 6,655,720 to Rampen, which are each incorporated by reference in their entirety. Other types of locking fasteners can be used, such as insertable and retractable L shaped latches, large bolts, screws, and the like, with or without turn knob ends as the bolt heads.

When fasteners 80 are moved to an unlock position, backrest (second platform) 30 can be removed from a vertical orientation against vertical frame 10, and moved to a horizontal bench configuration.

Referring to FIGS. 1B, 2, 3A, 3B, 4B, 5C, 6A, 6B, on the left leg 14 of vertical frame 10 there can be a first L-bracket 50 mounted thereon. Bracket 50 can have a perpendicular flange portion with a through-hole therethrough. Rotatably mounted to the lower horizontal beam 18 between hinges 40 can be a hinge 58 for a second L bracket 56 that also has a perpendicular flange portion with a through-hole there through. Across the top end 34 and bottom end 36 on the rear side 38 of the second platform 30 can be male shaped fastener(s) 93 protruding outwardly.

When the second platform 30 is moved into a horizontal position, a set of male fasteners 93 can be positioned into the through-holes in the perpendicular flanges of the vertical frame mounted

L brackets

50, 56. The opposite end of the second platform 30 can be placed on ledge 92 extending off of second vehicle mounted seat 90, and similarly held in place by male fasteners 93 mounted into female sockets (openings) 95 in the ledge 92.

The bench seat configuration can be moved back to a jump seat configuration by reversing the above process, and conversion method steps.

FIG. 9A is a perspective view of two seat conversion systems 1 and 100 inside of a vehicle with the jump seat configuration initially attached to a vertical frame 1 (here two vertical frame(s) 1 are inside the vehicle. FIG. 9B is another perspective view of the seat conversion systems 1, 100 of FIG. 9A in bench seat configurations inside the vehicle. Converting from jump seat to bench seat configurations, can follow the steps shown and described in reference to FIGS. 1-8B, and the bench seat configurations can be converted back to jump seat configurations by reversing the steps.

The invention can be used with on seating arrangement being a jump seat configuration and the other in a bench seat configuration. Also the conversion systems can be mounted between the left and right sides inside of a vehicle as well as extending behind the front seats inside of the vehicle.

Although the preferred embodiments show and describe the invention for use inside of a vehicle the seat conversion systems can be used inside of other structures, such as but not limited to inside buildings, homes, and the like. Additionally, the seat conversion systems can be used in other applications, such as outdoors, and the like, both attached to vehicles, or not part of vehicles.

While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
